All the talk about the "black death" proseal on the RV lists makes me chuckle. If you can't pound it or bend it the RV guys start panicking. You should hear them talk about the minuscule amount of fiberglass work they have to do. Hey, if any of you have an RV builder near you strike up a friendship. Help him out with his fiberglass work and you will have a friend for life. He will, in just about all cases, be glad to help you build a set of aluminum fuel tanks. It is no more of a big deal for him to help on a set of aluminum tanks than it is for you to help him out with a little composite work. Both of you already have the skills and tools. Back to aluminum tanks and proseal. If you have built your KR tail and wings and have put up with the epoxy and or vinyl ester then proseal is a walk in the park. Mix it up in the general ratio specified and just do it. It isn't sensitive to exact ratios, just may take a little longer to cure. When used on fuel tanks it just works. Try it, after you are flying, you will like it. Besides, we all ready have our epoxy work clothes. You will just have a little black to go along with the crusty amber epoxy. After all, as of my last RV newsletter, there are over 3,222 RV's flying and they all have proseal'd aluminum fuel tanks. Have to take a moment here and echo the sentiments of the KR builders that are flying rather than modifying/building. The fastest way into the air is build it to plans. But this is Experimental aviation and if you enjoy learning new methods and techniques then find an RV builder and make a new life long friend. They just have a bunch of scars from aluminum cuts rather than epoxy rashes and allergies.

My KR-1 Plans are one of Kens first ones (SN 69). When I get a chance to start on one It'll be a retract version. Bill Higdon Ed Janssen wrote "Russ, Yes, there have been many different "improved" versions of positive lock systems devised for the up and down positions for the retracts. Most I've seen over the years worked pretty good, although some were a bit complicated to operate. Quite a few designs are discussed in the archives - you may want to check them out. Being one of the KR "old timers", I personally prefer the looks of the KR with the wheels retracted (especially Don Betchan's KR-2's highly modified retracts that completely hide out within the wings and really give the plane a sleek appearance), although the tires stick out of the bottom of the wing a couple inches or so in the original design. Conventional (fixed) gear allows a bit longer prop to be used if needed, depending on the engine configuration. The shorter retracts haven't proved to be the best choice for rough fields either, as the plane will ride just inches from the grass. Most KRs you'll see these days will have the fixed gear option, which has proven to be probably the best overall configuration with regard to safety and simplicity. Dan Diehl converted his tailwheel KR-2 to fixed gear in "one long weekend", he's stated, but most guys will no doubt take much longer to do the job.

Would the extra power allow a higher pitched prop? Yes, increasing prop pitch absorbs more power. My 3100cc Corvair has turned a 58x74 at 2650 rpm statically, in a range where I'd "only" expect to get about 95 horsepower from this engine. That's about 100 rpm faster than an 0-200 would spin it. I would need to lower the pitch so I can get the rpm up to level where I can take advantage of the 3600 rpm that the engine needs to generate the 130 hp and 192 foot pounds of torque (see http://home.hiwaay.net/~langford/corvair/3100_ml.gif ). It's all a balancing act. I plan to use a 52 inch prop eventually. This one's just a loaner to keep my engine cool while breaking it in, but I'll bet I could fly behind it if I had to...

I holds 22 gallons and never leaked. Then Dana came along and built me some aluminum wing tanks using poop rivets and ProSeal. And from .032 aluminum sheet I might add. These tanks are awesome. The Proseal is amazing stuff and covers the pop rivets and seals the tank like the dew covers Dixie (southern terminology). Than Proseal is very flexible and has a rubber like consistency. In my opinion, the only way to build a tank. By the way, I still have my header tank even though I am not going to use it. I would offer it for sale or to the highest bidder but I custom built it to the width of my widened fuselage so I doubt there are very few KR's this tank would fit. If you are remotely interested let me know. Here is the link to my header tank: http://mywebpage.netscape.com/n886mj/tank.html sorry but there are no photos of the finished tank there but it will give you the idea how I did it.
